It's a poor test.
Question two is just plain wrong. Certain products can make your penis bigger. Alloderm is used in penile widening and post-surgical weights increase the the gains from phalloplasty. Some PE products do work, particularly the traction devices. Clearly the test creator is uninformed.
Question four and five are similar in that they're blaming a primary factor on a secondary factor. The primary factors, circulatory blockage and poor circulatory health, could be caused by eating fried foods or watching TV but those things in and of themselves do not cause circulatory problems. I could watch 10 hours of TV a day but if I'm doing it on a treadmill then I expect my circulatory health would be exceptional. I could eat two french fries a month and they will do nothing to decrease my circulation if I'm in otherwise good health.
The only one I got wrong otherwise was the condom question. I had thought polyurethane was better than latex. Either way I can't use polyurethane so I hadn't paid much attention but it's good to know.
